I just started with quail this year and the main thing I've come to realize about them is that they are absolute dirt worshipers. I give my caged quail a nice chunk of sod every day and they spend all day tearing it apart, playing, rolling, eating and sleeping in it. It keeps them well occupied. You might want to give that a try. I also have several hides and a high walled dust bath in each cage so they have a chance to get away from each other when they need to.
